So where does our fixation with Top Ten Lists come from, anyways? Letterman? The Ten Commandments? Well, if you can't beat 'em.....Here, for your casual perusal, is a chronological consideration of ten important Japanese SLRs that pushed the development of such cameras forward for over 30 years. This is not to say that these are the 10 "top" or "best" SLRs of all time (far be it for me to be the arbiter of such things ;-)), and some may be less familiar than others, but all of them had an undeniable effect on the industry or market as a whole. Let's dive in :-).

1957. A year of events that would reverberate for years to come. Sputnik. The debut of cable TV in the USA. "I Love Lucy" ended production. The Cat in the Hat was published. And a musical duo that would be as influential as anyone on the next two decades' of popular music (the Beach Boys, Beatles, and Bee Gees were only a few among the many that would cite themselves as being significantly impacted by them) had their first #1 hit:
1957 would also see the introduction of the first 35mm SLR from a relatively small Japanese manufacturer that was to have an outsized influence on the industry that would continue for over thirty years. In that year, TOPCON (Tokyo Kogaku) would find themselves at the leading edge of 35mm SLR technology and they would remain there for the next decade. The 1960s would see them emerge as Nikon's (Nippon Kogaku) most serious competitor in the professional 35mm SLR market. By 1977, however, Topcon's photography division would be a shell of its former self, outsourcing its remaining SLR production to Cosina and diving right to the bottom of the market. By 1981 (with Nikon owning over 75% of the pro market), Topcon was out of the photographic equipment business completely, even though they live on to this day in the industrial and medical optics arenas. So, what happened? How did Topcon go from industry leader to also-ran in the space of a generation?
Suffers from a quarter-century and counting film and manual focus SLR addiction. Has recently expanded into 1980's AF point and shoots, and (gack!) '90s SLRs. He even mixes in some digital. Definitely a sick man.
